IGINITION KEY SWITCH

1993 Ford Explorer

Having a problem with my 93 Ford Explorers steering columns Ignition cylinder key switch, it has became very loose, Have attempted to replace it but have Not found any correct information in books, nor videos showing, either, the right steering column, right steer model, Nor showing how to remove steering column covers and or steering wheel to access the locking pin that holds it in place. By the way? WHERE IS THE LOCKING PIN?
